Kromschroder Gas solenoid valve VAN125R/NWSR 88012160

The Kromschroder VAN125R/NWSR (SKU 88012160) is a normally open gas solenoid valve with a nominal diameter of 25 mm and a Rp 1" connection thread. It operates at a maximum inlet pressure of 500 mbar and requires a supply voltage of 230 V. The valve is suitable for natural gas, LPG, biogas, and air, and features a built-in pilot lamp for position indication. It is designed for use in tightness control systems and is compatible with VAS/VAD valves.

Parts of this type are selected by connection size, coil voltage, and function. Before ordering, verify the thread size (e.g., Rp 1") and the supply voltage (e.g., 230 V) match the existing installation. The valve may be installed with either IP54 or IP65 protection, depending on the version, and uses an M20 cable gland. Ensure the ambient temperature range (-20 to 60 °C) is suitable for the environment.

Common failure modes for this kind of valve include coil burnout, leaking valve seat, or a seized servo mechanism. Symptoms may include the valve failing to open or close properly, gas leakage, or the pilot lamp not indicating the correct status. Check the coil continuity, valve seat condition, and servo operation when troubleshooting.
